A free, independent calculator that estimates a veteran's combined VA disability rating and monthly pay. It applies the bilateral factor and combined ratings math with a step-by-step breakdown and uses VA's 2026 pay rates.
It also includes back pay, TDIU and SMC tools. It is not affiliated with the VA, and results are estimates only.

Veterans kept getting wrong combined ratings from simple addition, so I built a free, accurate, no-sign-up calculator using VA math.
